As described above, according to the stripping device for long onions of claim 1, a plurality of injection nozzles for injecting a pressure fluid are provided as a moving body which reciprocates between the leaf side and the root side of the long onions. The onion is provided so as to be rotatable by a predetermined angle about the substantial stem of the long onion, and when the moving body moves from the leaf side to the root side, the plurality of injection nozzles ejects pressure fluid and the long onion. Since it is configured to reciprocally rotate about the substantially stalk center by a predetermined angle, the pressure fluid is jetted to the entire stalk of the long onion, so that it can be peeled off neatly without leaving the outer skin of the long onion. Further, since the plurality of injection nozzles rotate about the stem of the long onion by a predetermined angle, the pressure fluid is sprayed around the stem, and the injection pressure of the pressure fluid can be set to a low pressure. Therefore, the long onions are not damaged when the pressure fluid is jetted. Furthermore, by making this injection pressure low, noise at the time of injection can be reduced and the capacity of the pressure fluid generation device can be reduced.

According to a second aspect of the present invention, the peeling device for long green onions conveys the long green onions one by one and conveys the same, and moves in synchronization with the conveying means, and at the same time, moves the long onions on the support. A moving body that reciprocates between the leaf side and the root side of the green onion,
Provided to this moving body, when this moving body moves forward from the leaf side to the root side, while ejecting a pressure fluid toward the substantial stem of the long onion, the substantial stem of the long onion is centered. Since the jet nozzle that reciprocally rotates by a predetermined angle and the peeling device that moves in synchronism with the moving body and forcibly peels the outer skin of the long onion peeled by the jet nozzle, are configured to be conveyed. The long onion S placed on the means is automatically peeled as it is during transportation, so that a large amount can be efficiently peeled. This brings about the maximum effect that the processing amount per device can be significantly increased as compared with the conventional one. Furthermore, according to this long green onion peeling device, long green onions can be continuously processed in a large amount.
It is possible to connect this long green onion to a sorting device for continuous and large-scale selection, and it is possible to realize a line from stripping long green onions to sorting, which is a great labor-saving effect in practical use.

Further, since the peeling device peels off the skin of the long onion that has been turned up by the injection of the pressure fluid, the peeling device forcibly peels off the skin of the long onion. It can be reliably peeled off, and the peeling effect is greatly improved compared to the conventional one.

Further, by providing the cutting means for cutting the leaves and roots of the long onions on the conveying means, it is possible to completely automate the peeling of the long onions to the length adjustment during the conveyance of the long onions. It has an extremely large practical effect.
